4. The method of claim 1, wherein the first information comprises at least one of: cell channel quality information, cell load information, information of a service to-be-transmitted, clock synchronization information, resource scheduling and configuration information, or cell interference information.
This invention relates to wireless communication systems, specifically methods for optimizing network performance by exchanging detailed operational data between network nodes. The problem addressed is the need for efficient coordination among cells in a wireless network to improve resource allocation, reduce interference, and enhance overall system efficiency. The method involves transmitting first information between network nodes, where this information includes at least one of the following: cell channel quality metrics, cell load status, details of services to be transmitted, clock synchronization data, resource scheduling and configuration parameters, or cell interference measurements. This data exchange enables dynamic adjustments in network operations, such as optimizing resource allocation based on real-time conditions, minimizing interference through coordinated scheduling, and improving synchronization across cells. The inclusion of multiple types of information ensures comprehensive decision-making for network management. Additionally, the method may involve transmitting second information, which includes at least one of cell identifier data, cell type information, or cell location details. This supplementary data further refines network coordination by providing contextual information about the cells involved. The combination of these information sets allows for adaptive and intelligent network management, leading to improved performance, reduced latency, and better utilization of available resources. The invention is particularly useful in dense wireless environments where interference and resource contention are significant challenges.
5. The method of claim 4, wherein the cell channel quality information comprises one of a reference signal received power (RSRP) or a reference signal received quality (RSRQ).
A method for wireless communication involves evaluating cell channel quality to optimize network performance. The technique measures signal strength or quality between a user device and a cellular network to determine the best available cell for connection. Specifically, the method uses reference signal received power (RSRP) or reference signal received quality (RSRQ) as metrics to assess channel conditions. RSRP quantifies the power level of a reference signal received from a cell, while RSRQ evaluates the signal quality by considering both power and interference levels. These measurements help devices select the most reliable cell, improving connectivity and reducing call drops or data interruptions. The method may also involve comparing these metrics against predefined thresholds or ranking multiple cells based on their signal quality to facilitate handover decisions. By leveraging RSRP or RSRQ, the approach ensures efficient resource allocation and enhances user experience in wireless networks. This technique is particularly useful in environments with varying signal conditions, such as urban areas with high interference or rural regions with limited coverage.
6. The method of claim 4, wherein the information of the service to-be-transmitted comprises at least one of: a period for triggering the service, a service packet size, a time offset of an arrival time point of the service within one period relative to a starting time point of the period, an arrival time window of the service within one period, a transmission time window of the service within one period, or a service tolerance delay.
This invention relates to wireless communication systems, specifically methods for managing service transmission in networks. The problem addressed is the efficient scheduling and transmission of services with varying timing and quality requirements, ensuring reliable delivery while optimizing network resources. The method involves determining and transmitting information about a service to be transmitted, including key parameters that define its timing and constraints. These parameters include the period at which the service is triggered, the size of the service packet, the time offset of the service's arrival within a given period relative to the period's start, the arrival time window of the service within a period, the transmission time window of the service within a period, and the service's tolerance delay. These parameters allow the network to accurately schedule and prioritize service transmissions based on their specific requirements, ensuring timely and efficient delivery. The method also involves receiving and processing this service information to generate a transmission schedule. This schedule is then used to control the transmission of the service, ensuring that it is delivered within the specified constraints. The method may also include adjusting the transmission schedule dynamically based on network conditions or changes in service requirements, ensuring adaptability and reliability in service delivery. This approach improves network efficiency and service quality by aligning transmission timing with the specific needs of each service.
